FX-SCH-A-000600: Check the tax type for the invoice discount

What it means

For a discount on the whole invoice (BG-20), this rule checks ram:CategoryTradeTax/ram:TypeCode inside ram:SpecifiedTradeAllowanceCharge where ram:ChargeIndicator/udt:Indicator is false. This tax type is separate from the VAT category (BT-95). A non-empty value must be allowed by the profile's tax type code list. An empty value passes this code-list check.

Why it matters

The tax type identifies the tax to which the discount's category belongs. It is not the VAT category or the VAT rate.

How to fix it

Check the tax type assigned to your invoice discount. If you generate the XML yourself, set ram:CategoryTradeTax/ram:TypeCode to VAT in the header-level ram:SpecifiedTradeAllowanceCharge whose ram:ChargeIndicator/udt:Indicator is false. Generate the file again and recheck it.
